PRICE-COMPUTING SCALE.

SPECIFICATION forming part of Letters Patent N 0. 651,116, dated June 5, 1900.

Application filed August 23, 1895. Serial No. 560,271. (No model.)

To all whom it may concern:

Be it known that I, ORANGE O. OZIAS, of

.Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Price Computing Scales; and I do hereby declare the following to be a f all, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

This invention relates to that class of computing-scales wherein a movable poise is employed with a plurality of graduations representing different valuesyby which mechanism weight and values are indicated together, the weight by said poise and the value by said graduations.

The present invention has for its object to improve the construction and increase the capacity, utility, and compactness of computing-scales whereby they are rendered more effective in operation, the values are indicated more distinctly, and the neat and compact form obtained renders them more desirable by reason of the small space required in proportion to the capacity in weight and values.

Heretofore in machines of this character with which I am familiar the beams of computing-scales have been provided with a plurality of value indicating graduations arranged to extend between the supportingpivot of said beam and its outer or counterpoise pivot, said value graduations being carried directly by or adjacent to said beam and independent thereof. My present invention is believed to involve a new and novel construction in this class of machines by reason of the fact that the value-indicating graduations are arranged on a member or tablet arranged to extend on both sides of the beamsupporting pivots substantially the fulllength of the scale beam or lever and supported in extensions or arms on the beam; which novel construction greatly increases the compactness of scales of proportionately-large capacity and renders the value graduations clear, distinct, and uncrowded.

The improvement furthermore consists in new and novel structures and combinations and arrangements of the parts, as hereinafter described, and more fully pointed out in the annexed claims.

Referring to the drawings, Figure 1 is a rear elevation of a simple even-balanced scale embodying my invention. Fig. 2 is a sectional view of the computing-cylinder and the means for mounting it. Figs. 3 and 4 illustrate details of construction, and Fig. 5 is a reverse perspective view of the scale with the base-piece B. The beam A is bifurcated or 1 formed with an opening extending vertically therethrough at the central portionof said beam for separating the knife-edge bearings 12, and thus bringing their hardened seats at some distance from the longitudinal center of said beam A. The opening formed by beam A being bifurcated also admits of the passage of a vertical rod B, supported by a rigid bifurcated casting B having hardened seats in its downwardly-extending arms to receive knife edge bearings 6 rigidly securedinbeam A. This casting B is surmounted by a preferably-circular cap-piece B to which the scoop-retaining spider B is secured in the instance shown, or to which a platform may be directly securedwhen desired. B extends downward through the hollow column and into the cavity usually formed in The rod I the base B, where said rod is provided with 1 a gravity-weight or pivoted to a retaininglever, which in turn is pivoted to said base or other well-known means for maintaining the vertical 'alinement of rod B.

To the left (in Fig. 1) of the supportingpivots of beam A said beam is provided with laterally-extendingarms a, carrying a thread ed screw a, upon which is mounted in the usual manner a balance-poise (L as shown. To the left of the supporting-pivots of beam A said beam is provided with a loop a engagingwith a projection 73 of cap b forlimiting the movement of said beam.

The beam proper, A, is provided with a I graduated bar or supplemental beam A, upon which a poise slides and is adapted to indicate weight. The graduated bar may be attached to and supported by the beam A in any suitable manner; but I preferably arrange at the ends of the beam A extensions 0, projecting forward and having their ends arranged ver tically for a purpose to be presently explained, and the graduated bar is attached to' and supported by these extensions. Such arrangement, in effect,forms a rigid structure, the whole of which may be said to constitute the beam, and at each end thereof or on opposite sides of the pivotal center the said beam is provided with vertically-arranged extensions, formed by the ends of the parts 0, and between these vertically-arranged extensions I journal the rotary member carrying the sets of grad nations for indicating the cost of articles weighed. In the preferred arrangement the rotary member is in the form of a cylinder having peripheral grad nations and marks indicating the cost of articles at different rates per unit-as shown, for instance, in the patent to Kepler, No. 51 t,475although any desired markings may be used.

I prefer to form cylinder 0 of paper or other material of such thickness as to give the proper degree of stability to said cylinder, or to employ thin paper or material and reinforce it with one or more thicknesses of like or unlike material to render said cylinder stiff enough to maintain a substantiallyuniform contour.

The preferred manner of mounting cylinder C is upon headpieces C, at opposite ends provided with circumferential tapering flanges C to accommodate the slightly-varying diameters of said cylinder and to prevent said headpieces from passing completely into the bore of said cylinder. The headpieces C I prefer to make of spun or stamped metal, with a cast bushing or hub (J secured thereto. The hubs C of headpieces (J are screwthreaded and are adjustably mounted upon shaft S by engaging the screw-th reads formed near both ends of said shaft, while said headpieces 0 are rigidly held in the desired position by lock-nuts C in contact with their hubs C The shaft S is held from longitudinal movement by having its ends bearing in frames 0 0, smaller in diameter than the central body of said shaft. The object of this adjustment will be hereinafter fully referred to.

Completely enveloping the cylinder 0 is a covering D, rigidly secured to the frames 0 O and provided with alongitudiual aperture D, through which the graduations or charact-ers on cylinder C are exposed to View. The graduated bar orsupplemental beam A is provided with a sliding poise A adapted to indicate weight, said poise A being also provided with a downwardly-extending hand or pointer A to indicate the proper value graduation appearing in aperture D.

As the weight indicating beam and the value-indicating cylinder are independent, when assembling the manufactured part-s great difficulty is experienced in readily securing the proper alinement between the weight and value graduations in order that the weight and value may both be indicated correctly. This difficulty I prefer to overcome by adjustably mounting the cylinder 0 upon its shaft S preferablyin the manner shown and described, although any other form of adjustment may be employed with equal effectiveness any without departure from the spirit of the invention as involved in this feature of the improvement.

To facilitate the operation of the scales manufactured under Letters Patent No. 514,475, I provide at the extreme left of beam A, Fig. 1, a knife-edge pivot E, snpportinga loop E, which loop may receive the hooked rod E carrying its integral counterweight when weighing and computing articles of high value. WVheu weighing and computing articles of low value, the hooked rod E with its integral counterweight E maybe supported by a projection E of cap b One end of shaft S projects beyond one of the frames 0 (J and has secured thereto a thumb-nut or hand-wheel E for the purpose of revolving cylinder 0 secured to said shaft.

To those conversant with this art it is evident that in the operation of this device the weight of an article is indicated by the beam A, and also by the removable counterweight E when said weight is employed, while the values of predetermined quantities of an article at the desired price per pound are exposed to View through aperture D, and the particular value of said article designated in each instance by pointer A on poise A The scoop-retaining spider 13 is provided with npwardly-diverging arms G, having apertures in their extreme ends for receiving the shanks I of and projecting from enlarged rubber or felt tips J, the remaining ends of said shanks I being provided with a slightlyenlarged portion K. The shanks I are of uniform diameter, for a distance equal to the thickness of arms G, in order -'that said enlarged portion K thereof may be forced through the aperture, and in expanding to its normal size said enlarged portion K firmly secures the enlarged rubber or felt tips J to the arms G of spider B These tips J prevent the marring of the scoop and lessen the jars upon the knife-edge pivots.

Having now described my invention, what I claim as new, and pray to secure by Letters Patent, is-
